Collective modes near a Pomeranchuk instability
Avraham Klein, Dmitrii L. Maslov, Lev P. Pitaevskii +1
We consider collective excitations of a Fermi liquid. For each value of the angular momentum , we study the evolution of longitudinal and transverse collective modes in the char…
Decay of the relative phase domain wall into confined vortex pairs: the case of a coherently coupled bosonic mixture
Albert Gallemí, Lev P. Pitaevskii, Sandro Stringari +1
A domain wall of relative phase in a flattened harmonically-trapped Bose-Einstein condensed mixture of two atomic hyperfine states, subject to a stationary Rabi coupling of intensi…
Magnetic defects in an unbalanced mixture of two Bose-Einstein condensates
A. Gallemí, L. P. Pitaevskii, S. Stringari +1
When the spectrum of magnetic excitations of a quantum mixture is much softer than the density spectrum, the system becomes effectively incompressible and can host magnetic defects…
Collisionless sound in a uniform two-dimensional Bose gas
Miki Ota, Fabrizio Larcher, Franco Dalfovo +3
Using linear response theory within the Random Phase Approximation, we investigate the propagation of sound in a uniform two dimensional (2D) Bose gas in the collisionless regime.…
Spin-orbit-coupling induced localization in the expansion of an interacting Bose-Einstein condensate
Chunlei Qu, Lev P. Pitaevskii, Sandro Stringari
By developing a hydrodynamic formalism, we investigate the expansion dynamics of the single-minimum phase of a binary spin-orbit coupled Bose-Einstein condensate, after releasing f…
Magnetic solitons in Rabi-coupled Bose-Einstein condensates
Chunlei Qu, Marek Tylutki, Sandro Stringari +1
We study magnetic solitons, solitary waves of spin polarization (i.e., magnetization), in binary Bose-Einstein condensates in the presence of Rabi coupling. We show that the system…
